1.1.8.6 If the Contractor observes that any of the Contract Documents are at variance therewith

in any respect, he shall promptly notify Consultant in writing, and any necessary changes shall be accomplished by appropriate modification. It is not the Abatement contractor's responsibility to make certain that the Contract Documents are in accordance with applicable laws, statutes, building codes and regulations. If the Abatement contractor performs any work knowing it to be contrary to such laws, ordinances, rules and regulations, and without such notice to Consultant, he shall assume full responsibility therefore and shall bear all cost attributable thereto.

HES Project No. 20-755-11624 01000-5


1.4 DEFINITIONS:

1.4.1 GENERAL EXPLANATION: A substantial amount of specification language constitutes definitions for terms found in other contract documents including the drawings. Drawings must be recognized as diagrammatic in nature and not completely descriptive of the requirements indicated thereon. Certain terms used in contract documents are defined in this article. Definitions and explanations of this section are not necessarily either complete or exclusive but are general for the work to extent they are not stated more explicitly in another element of contract documents.

1.4.2 GENERAL REQUIREMENTS: The provisions or requirements of Division-1 sections apply to entire work of Contract, and where so indicated, to other elements which are included in the project.

1.4.3 INDICATED: The term "indicated" is a cross-reference to graphic representations, notes, or schedules on drawings, to other paragraphs or schedules in the specifications, and to similar means of recording requirements in contract documents. Where terms such as "shown", "noted", "scheduled", and "specified" are used in lieu of "indicated", it is for purpose of helping the reader locate cross-reference, and no limitation of location is intended except as specifically noted.

1.4.4 DIRECTED, REQUESTED, ETC: Where not otherwise explained, terms such as "directed", "requested", "authorized", "selected", "approved", "required", "accepted", and "permitted" mean "directed by the Consultant", "requested by the Consultant", and similar phrases. However, no such implied meaning will be interpreted to extend the Consultant's responsibility into Contractor's responsibility for construction supervision.

1.4.5 APPROVE: Where used in conjunction with the Consultant's response to submittals, requests, applications, inquiries, reports, and claims by Abatement contractor, the meaning of the term "approved" will be held to limitations of the Consultant's responsibilities and duties as specified in General and Supplementary Conditions. In no case, will "approval" by the Consultant be interpreted as a release of Abatement contractor from responsibilities to fulfill requirements of contract documents.

1.4.6 FURNISH: Except as otherwise defined in greater detail, term "furnish" is used to mean supply and deliver to project site, ready for unloading, unpacking, assembly, installation, etc., as applicable in each instance.

1.4.7 INSTALL: Except as otherwise defined in greater detail, term "install" is used to describe operations at project site including unloading, unpacking, assembly, erection, placing, anchoring, applying, working to dimension, finishing, curing, protecting, cleaning, and similar operations, as applicable in each instance.

1.4.8 PROVIDE: Except as otherwise defined in greater detail, term "provide" means furnish and install, complete and ready for intended use, as applicable in each instance.

1.4.9 INSTALLER: The term "installer" is defined as the entity (person or firm) engaged by Abatement contractor, or its subcontractor or sub-subcontractor for performance of a particular unit of work at project site, including installation, erection, application, and similar required operations. It is a general requirement that such entities (installers) be expert in operations they are engaged to perform.

1.4.10 PROJECT ADMINISTRATOR: The entity described as the "Project Representative" in AIA Document A201 "General Conditions of the Contract for Construction". The Project Administrator is a representative of the Owner at the job site with authority to stop the work upon verbal order if requirements of the contract documents are not met or if in the sole judgement of the Project Administrator, the Consultant, Owner, the interests of the Owner, safety of any person or the Owner's property are jeopardized by the work.

2.22.8 Using glove-bags, workers in full protective body clothing and respirators may begin removal of insulation as per the following, and/or manufacturer's instructions and OSHA requirements. In case of conflict, the more stringent provisions shall apply:

2.22.8 At least two workers shall be assigned to each glove-bag.

2.22.8 Cut the sides of the glove bag to fit the size of pipe to be worked on and insert the tools into the attached tool pocket.

2.22.8 Attach the glove-bag, to the working area, by folding the open edges together and sealing with staples and tape. Any additional support, which may be necessary to support the weight of the debris shall be provided.

2.22.8 Seal the edges of the glove-bag around the working area with tape or adjustable straps to form a tight seal. Slice open the side port to allow entry of the wetting tube and HEPA vacuum hose. Insert the nozzle from the portable sprayer, seal around it with tape, and thoroughly wet the area to be removed.

2.22.8 Insert arms into the armholes and gloves and proceed to remove the asbestos from the elbow, valve fitting or pipe. At locations where the insulation rests directly on pipe hangers or supports, the abatement contractor shall re-support the pipe by shimmying with wood blocks or other suitable materials. Continue wetting the material as required. Thoroughly wet the remaining pipe and insulation and wash down the inside of the glove-bag. Scrub or brush any remaining suspect insulation material from the pipe or fitting.


HES Project No. 20-755-11624 01000-31


2.22.8 The tools shall be pulled through one of the glove inserts, thus turning the gloves inside-out. Twist, tape around the twist, and cut through the tape to remove the glove with the tools. This glove may then be placed into the next glove-bag. When glove-bag operations are complete, clean tools by cleaning any residual materials from tools and disposing of glove-bag and water as contaminated waste.

2.22.8 When the job has been completed, remove the spray nozzle, insert the HEPA vacuum nozzle, and turn on the HEPA vacuum to remove air from the bag. With the air removed from the glove-bag, squeeze the bag tightly as close to the top as possible and twist seal and tape to keep the asbestos material safely at the bottom of the bag. Turn off the HEPA vacuum, remove the hose from the side port, and seal the side port with tape.

2.22.8 Cut and remove the glove-bag from the working area and place it into another plastic bag. Move bags to holding area or disposal storage unit.

2.24.8 Mist surface of protective polyethylene and carefully fold inward. Proceed to HEPA vacuum the work area for any residual materials and seal the exposed edges and piping with the proper encapsulant sealants.

2.23 DISPOSAL OF ASBESTOS-CONTAINING WASTE (SOLID AND/OR LIQUID):

2.23.1 As the work progresses, to prevent exceeding available storage capacity on-site, workers from uncontaminated areas in full protective clothing and dual cartridge respirators shall enter the equipment decontamination unit and place the appropriate supply of specified containers within the holding room. Workers in the holding room shall be passed sealed, bagged material. Half full bags shall be placed in a second container (bag or drum). Store or dispose of waste materials. Ensure all curtained doorways are closed. Ensure that all containers are sealed properly before removing for transport and disposal. The color of the disposable clothing worn outside the work area shall be a different color than the disposable clothing worn inside the work area. At no time, shall a removal worker pass the curtained doorway between the holding room and the wash room. Drums will not be required if abatement contractor uses sealed bins or enclosed trucks to store and transport double-bagged waste.

2.23.2 Prepare and sign the Waste Shipment Record (WSR) for each load of asbestos-containing waste transported off site. Ensure that the WSR is completed by the transporter(s) and waste disposal site operator.

2.23.3 Mark vehicles used to transport asbestos-containing waste material during the loading and unloading of waste in compliance with 40 CFR 61, Subpart M and during the transport of asbestos-containing waste in compliance with 49 CFR 171 and 172.

2.23.4 Vehicles used for transporting asbestos-containing materials to disposal sites shall have a completely enclosed, lockable storage compartment if drum requirement is to be deleted. Storage compartments shall be plasticized and sealed with a minimum of one (1) layer of 6-mil polyethylene on the sides and top and two (2) layers of 6-mil polyethylene on the floor. The compartments shall be thoroughly wet cleaned and/or HEPA vacuumed following the disposal of each load of material at the dump site. At the conclusion of the project (or before transport vehicles are used for other purposes), the polyethylene shall be properly removed and disposed of as contaminated waste. After this is accomplished, compartments shall once again be wet cleaned and/or HEPA vacuumed in order to eliminate all debris prior to being returned to the rental company. All plastic sheeting, tape, cleaning material, including mops and sponges, clothing, filters, and all other contaminated disposable materials shall be packaged, labeled, and disposed of as asbestos-containing waste.

2.23.5 Dispose of materials at an authorized disposal site in accordance with the requirements of federal, state and local disposal authorities.


HES Project No. 20-755-11624 01000-32


2.23.6 Workers unloading waste material at the disposal site shall be dressed in full-body protective clothing and dual cartridge respirators.

Is there any reason we can’t patch the existing terrazzo floor inside the restrooms where

wall demolition and floor mounted toilets are removed in lieu of providing an all new tile

floor? If so, we would also need to patch the cove base where the wet walls are being

demolished.
